# Lower Limb Deep Venous Thrombosis After Posterior Spinal Fusion as an Initial Manifestation of Factor V Leiden Mutation in a Pediatric Patient: A Case Report

## TL;DR

A 12-year-old girl developed a blood clot after spinal surgery due to an undiagnosed genetic condition, highlighting the need for awareness in pediatric cases.

## Contribution

This case report highlights Factor V Leiden mutation as a rare cause of DVT in pediatric spinal surgery patients with no prior history.

## Key findings

- A pediatric patient developed DVT after spinal fusion due to an underlying Factor V Leiden mutation.
- The patient had no prior thrombotic events or family history of clotting disorders.
- The case emphasizes the importance of screening for genetic clotting disorders in at-risk pediatric surgical patients.

## Abstract

Deep venous thrombosis (DVT) is a serious condition in which a blood clot forms in a deep vein, usually of the lower extremity. In pediatric orthopedic surgery, the incidence of thrombotic events is rare. This is a case presentation of a 12-year-old female patient without previous events or a family history of thrombotic events who underwent a posterior spinal fusion due to severe adolescent idiopathic scoliosis. The patient developed a DVT due to an underlying Factor V Leiden mutation. The purpose of this case report is to create awareness, facilitate the diagnosis and management, and aid in future interventions and clinical outcomes.
